- The. operation-of athe counting.:rcir ut; and hai key identifier units, over which the present invention is an improvement, is detailed in applicants U. S. Patent No. 2,313,627, issued March 9, 1943, and U. S. Patent No. 2,325,744, issued August 3. 1943, respectively. Therefore, only so much of their operation will be described herein as is necessary adequately to disclose the operation of the present invention.

Referring now in detail to the Fig. 1, 9 designates a treadle imbedded in a roadway, transversely thereof and adapted to be traversed by vehicles passing over the roadway. Mounted in the treadle 9 are a plurality of pairs of elongated parallel contacts, I, IA; 2, 2A; 3, 3A and 4, 4A. Said pairs of contacts constitute switches normally open but which may be successively closed and opened as the wheels of a vehicle roll over the treadle. The contacts I, 2, 3 and 4 are connected to the plus side of an electric power supply. Preferably, the switches are spaced apart not more than three inches so that as the front and rear wheels of a vehicle roll over the treadle, the switches will be closed successively and adjacent switches will be concurrently closed.

The switches are connected by a circuit C of Fig. 1 so arranged, as will appear hereinafter, that the operation of the treadle in the proper or forward direction in which trafiic in the reversible lane is being passed, will actuate a counter F, termed the forward counter, while wheels of a vehicle "backing up over the treadle will operate a second counter R, termed the rearward counter.

The forward counter F comprises a relay 1t having a coil 1I, one side of which is connected to the minus power supply. Said relay, when energized, is adapted to open a switch arm 19 which is normally in engagement with a fixed contact 13a. Said relay controls armature 19a adapted to advance ratchet wheel 1% carried on a shaft which also carries the usual printing wheels. A representation of the face of the printing wheels showing an arbitrary forward count is shown below said ratchet wheel b.

The rearward counter R comprises a relay 80 having a coil 8 I, one end of which is connected to the minus power supply. Said relay, when energized, is adapted to open a switch arm 84 which is normally in engagement with a fixed contact 84a. Said relay controls armature 80a, adapted to advance ratchet wheel 80b carried on a shaft which also carries the usual printing wheels. A representation of the face of the printing wheels showing an arbitrary reverse count is shown below said ratchet 80b.

Reverse lane operation solenoid I51 has a coil I58, one end of which is connected to the minus power supply. Associated with said solenoid are switch arms I59 and I68, normally in engagement with fixed contacts I53a and IBM and adapted to move out of engagement with said contacts and into engagement with fixed contacts I 53b and IBM), respectively, when said relay is energized. Said solenoid is also adapted to move printing slug I13 into a printing position so that the letter R will be printed along with the forward and rearward axle totals only when said solenoid is energized.

Part D of Fig. 1 represents a toll collection booth at a reversible lane showing switches associated with a normal direction key identifier unit and a reverse direction key identifier unit and connections to a trafilc signal system.

Switch I 66 is normally in an open-circuited position and is adapted to be moved into engagement with switch contact I861: when an identifier key is inserted and turned in the reverse direction key identifier unit. Trafilc light controlling switch arm I61 is normally in engagement with contact arm I61!) and adapted to be moved out of engagement therewith and into engagement with switch contact I610. when said reverse key identifier is operated.

Switch arm I68 is normally in engagement with switch contact I68?) and is adapted to move out of engagement therewith and into engagement with switch contact I68a when the identifier key is inserted and turned in the normal direction key identifier unit.

Fig. 2 shows the mechanical operation of the reverse lane operation solenoid with respect to the printing slug I13. It can be seen that when solenoid IE1 is not energized printing slug I13 is in a position removed from the printing position indicated by the line A-A falling along the face of the printing wheels. When solenoid I51 is energized (the condition representative of reverse lane operation) its armature I14 pivotally connected to lever I15 moves inwardly in a direction as indicated by the arrow. Said lever, having its fulcrum at fixed pin I16, moves printing slug I13 at the remote end of lever I15 into its printing position along the line A-A. Spring I11, fixed at one end and connected at the other end to the lever at a point between the slug end and the fulcrum serves to move said lever and its slug out of printing position when solenoid I51 is deenergized.

The circuit C comprises four relays designated by numerals Ill, 20, 30 and 40. Relay III has two windings II and I2 connected together and to a minus power supply. Associated with relay III are movable switch arms I3, I4, I 5 and I6. Switch arm I3 is normally in engagement with a fixed contact I3a. and is adapted to be moved by the relay I 0 into engagement with a fixed contact I312. The switch arm I4 is normally open and is adapted to be moved by the relay I0 into engagement with a fixed contact I4a. Switch arms I 5 and I6 are normally open, but are adapted to be moved by the relay I 0 into engagement with fixed contacts I 5a and I6a, respectively.

Relay is provided with a coil 2| connected at one end to a minus power supply. Associated with said relay are switch arms 22, 23, 24, 25, 26 and 21. Switch arms 22, 24, are normally open and are adapted to be moved by the relay 20 into engagement with fixed contacts 22a, 24a and 25a, respectively. Switch arm 23 normally engages a fixed contact 23a and is adapted to be opened by the relay 20. Switch arm 26 is normally in engagement with a fixed contact 26a, but is adapted to be opened by the relay 20. Switch arm 21 is normally in engagement with a fixed contact 21b but is adapted to be opened by the relay 20.

Relay 30 is provided with a coil 3| connected at one end to the minus power supply. Said relay.

controls switch arms 32, 33, 34, 35, and 31. Switch arms 32, 34 and 35 are normally open but are adapted to be moved by said relay into engagement with fixed contacts 32a, 34a and 35a, respectively. Switch arm 33 is normally in engagement with a fixed contact 33a and is adapted to be opened by said relay 30. Switch arm 36 is normally in engagement with afixed contact 36a and is adapted to be opened by the relay 30. Switch arm 31 is normally in engagement with afixed contact 311) but is adapted to be moved out cult is through switch 25, a, wire 1, switch I5, I5a, wire I09 and coil I2, to the minus side of an electrical power supply.

Following through the motion of the wheels over the treadle 9, switch I, IA will open and switch 3, 3A will be closed while switch 2, 2A is still closed. In closing switch 3, 3A, relay will be energized by the circuit from the plus side of a source of electric power through switch 3, 3A, wires I01 and 49, and the coil 3| of relay 30 to the minus side of a source of electric power. Energization of relay 30 closes switches 32, 32a; 34, 34a and 35, a and opens switches 33, 33a; 36, 36a and 31, 312).

In closing switch 3, 3A, and by action of the energized relay 30, a circuit is completed to hold relay 20 energized even if switch 2, 2A is opened. The completed circuit is through switch 3, 3A, wire I01, switch 34, 34a, wire 50, switch 52, 52a, wire 12, switch 24, 24a, wire 28a and coil 2| of the relay 23.

Still following the passage of the wheels over the treadle 9 in the direction indicated on the drawing, switch 4, 4A will close and switch 2, 2A will open while switch 3, 3A is still closed.

Closing switch 4, 4A will provide a circuit energizing relay 50, the circuit being through coil 5| of relay 50, wire 11, switch 32, 32a, wire 1%, switch 22, 22a, wires I20 and I5, switch I3, I31), wire 19 and switch 4, 4A. Energizing relay 5% will close switches 53, 53a; 54, 54a; 55, 55a and 58, 53a, and will open switches 52, 52a; 56, a and 51, 51a. By closing switch 55, a, another energizing circuit for relay 50 is completed, the purpose of which will be hereinafter apparent. This second circuit may be traced from minus power supply through coil 5| of said relay, wires 11 and 85, switch 84, 84a, wire 88, switch '59, 19a, wires 86 and I2I, switch 55, 55a, wires I3 and switch I3, |3b (the relay It being energized) wire 19, through closed switch 4, 4A, to plus power supply. In closing switch 53, 58a another circuit will be completed holding the relay II) ener gized through coil II of said relay, the circuit being through switch 58, 58a, wire 83, switch I4, I4a; wire 0 and coil II.

Opening switch 52, 52a will break the previously described circuit holding relay 20 energized through switch 3, 3A. Switch 2, 2A has also been opened by the wheel rolling off the lane, breaking the circuit through said switch and coil 2| of relay 20. Relay 20 is then deenergized. De-energization of relay 20 will allow switches 23, 23a; 25, 20a and 21, Z'Ib to close and will allow switches 22, 22a; 24, 24a; and 25, 25a to open.

De-energization of relay 20 serves to complete a holding circuit for relay 50 in its energized condition, for the purpose hereinafter appearing. The second circuit for relay 5%] holds said relay energized while switch 22, 22a opens upon de-energizing relay 20. This holding circuit is from the negative side of a source of electrical energy, through coil 5| of relay 50, wires I1 and 85, switch 84, 84a, wire 88, switch 19, 19a, wire 86, switch 54, 54a, switch 21, 21b and through wire 38 to the positive side of a source of electrical energy.

The further progression of the wheels over the treadle 9 will open switch 3, 3A de-energizing relay 30. Switches 33, 33a; 36, 36a and 31, 311) will then close, and switches 32, 32a; 34, 34a and 35, 35a will then open. Opening of switch 3, 3A will energize the directional forward counter F, the completed circuit being through coil 1| of counter relay 10, wire I64, switch I60, I60a, wire IOI, switch l6, Ilia, wires I02 and I03, switch 53, 53a, wires |3| and I04, switch 36, 36a, wire I 00, and switch 26, 20a. Counter relay 10 will then register one count on the counter F. The actuation of counter F will open switch 19, 19a and hence break the holding circuit for relay 50 through said switch. It will not be noted that relay 50 was held in energized condition until counter F was actuated irrespective of the condition of the last two treadle switches 3, 3A; 4, 4A to insure a count even if the wheels pass over the treadle at a great rate of speed. Deenergized relay 50 will allow switch 58, 58a to open, opening the circuit of coil II of relay I0, thereby de-energizing relay I0. All the switches of the treadle are then opened and all relays are de-energized.

The operation of the circuit as described would be similar were all the steps in the operation of the circuit taken in the reverse order. The closing of switches in the sequence 4, 4A; 3, 3A; 2,

2A and I, IA will operate the backward counter R.

circuit connections (wires |0I and I06) to counter relays 10 and 80. At the same time printing slug I13, associated with solenoid I51 is moved into a printing position, thereby allowing its print to be made whenever an axle count print is made. This printing serves to indicate on the printed record when the system is in the reverse lane operation. As illustrated in Figure 3, the printed record 200 has two groups of columnar numerical1 representatives MI, 202 respectively, printed thereon. The column 20| is printed from the settings or the forward counting printing wheels, while column 202 is taken from the settings of the rearward counting printing wheels. Column 20I is further divided into two groups of consecutive numbers, as at 20|a and 20Ib. Group 20|a represents the last three axle counts of vehicular traffic travelling on the lane and crossing the treadle in normal traffic direction. After count 2367 was made, the reverse direction identifier key was actuated to effect energization of solenoid I51 which moved printing slug I13 into printing position. As hereinbefore described, the directional counters were similarly reversed with the energizing of solenoid I51. Thus, the first axle traversing the treadle in the reverse direction will effect a consecutive count on the forward counter as shown in Figure 3, as 2368. A printing hammer and inking mechanism, not shown, is

arranged to press record 200 against the counter digit wheels with each counting operation and imprint thereon, the respective numerals. With slug I13 in printing position, the first count and all subsequent counts of the reverse traflic flow will effect the printing of the reverse identification character R, along with the total count. Therefore, record 200 will readily show the number of axle counts occurring in each of the directional periods. Obviously, when trafilc direction is again returned to normal direction, the actuation of the respective identifier key will de-energize solenoid.
